示例1: ApplyLanguageModelOnTheFly
/**
* Constructor. Initializes on-the-fly composition with a language model.
* \param fst Machine you want to apply the language to. Pass a delayed machine if you can, as it will expand it in constructor.
* \param model A KenLM language model
* \param epsilons List of words to work as epsilons
* \param natlog Use or not natural logs
* \param lmscale Language model scale
